How can I propagate user state across the backend and frontend?
I’m building an app using TanStack Start and Better-Auth. I want to fetch and access my user state or information during the beforeLoad or loader lifecycle hooks.
I’ve seen examples where people put their user fetching logic in the beforeLoad of the __root layout, but when I do that, my page fails to load. Is this the correct approach to handle user state fetching? If not, what is the recommended way to propagate user state across both backend and frontend?

im struggling to understand where you populate the user property inside the context. The
$$auth middleware is only used in server functions. Do they populate it and because you're on ssr mode, have access to it in beforeLoad?generous-apricot•5mo ago
see in __root.tsx beforeLoad,
i use the queryClient to fetch the user thanks to userQueryOptions, which calls this server function
